  • Simultaneous immobilization of ammonium and phosphate from aqueous solution using zeolites synthesized from fly ashes

    Zeolites were synthesized from silica-rich (SF-Z) and calcium-rich (CF-Z) fly ashes, respectively, and their performance in immobilizing ammonium and phosphate was investigated through batch experiments. The cation exchange capacity and phosphate immobilization capacity of SF-Z were identified as 2.79 meq/g and 12.97 mg/g while those of CF-Z were 0.69 meq/g and 87.41 mg/g, respectively. The ...

  • Investigation of a direct melting dehydrated sewage sludge pilot plant

    A direct melting dehydrated sewage sludge furnace was tested to obtain the basic operating parameters. Observation of particles (fly ash and deposited particulates) inside the pilot plant was performed to determine the particle properties. The results showed that dehydrated sewage sludge could be directly melted at a temperature of 1400?C with stable combustion. With regard to the fly ash, the ...

  • Durability evaluations of bridge deck high–performance concrete

    Although several information are available on various aspects of durability of high–performance concrete (HPC), no systematic information is available on durability of HPC used for bridge decks. In this study, 12 HPC mixtures were prepared with different combinations of fly ash, slag, and silica fume with three different w/cm ratios: 0.40, 0.35, 0.30 to study the durability primarily ...
